Nonspecular meteor trail altitude distributions and durations observed by a 50 MHz high‐power radar
durations observed trail altitude distributions
2017/3/22
High‐power large‐aperture (HPLA) radars frequently observe nonspecular meteor trail
echoes that result from plasma turbulence driven by the intense pressure gradients on
the trail edges. This paper ...
